Welcome to TechIMO.
To help you further we are going to need a little more info. How much exactly are you willing to spend? And are the above the only components you have?
Cos you still need: monitor, case, psu, OS, mobbo+cpu, keyboard+mouse and all of the other inside bits.
Do you have any of the above that can be reused?
Also are you in america or europe etc. as this will affect where you buy and how much it will cost.
